Abstract: Labels for file folders that each has a self-adhesive backed surface and in a non-folded position has a front surface with a given letter of the alphabet printed on one half and the same letter of the alphabet printed on the other half at right angles to the first mentioned letter for permitting the label to be used either for top tab filing or end tab filing. In either case, with the label properly positioned on the file folder, and the file properly placed in a vertical position in a file cabinet, one letter will be upright on the desired side of the tab to which the label is adhered. Thirteen distinctive colors are keyed to the first 13 letters of the alphabet as a solid block, and the same 13 colors are used for the second half of the alphabet with strips (bands) through the colored portions of the labels.
